== Experiment Plan ==

For each beam delivery, our acquisition time is 5 seconds. This gives us an optimal number of events. For FLASH beam time restrictions, we could consider reducing the acquisition time, if necessary.
* Set up mains cabling and networking in treatment and control rooms.
** no beam
* Install Peli case on treatment couch.
** no beam
* Background
** no beam
* Calibration shoot-through measurements of 4 stack modules: either rotating case or modules for back shoot-through:
** 8 beam deliveries 245 MeV conventional current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at conventional current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
** 8 beam deliveries 245 MeV FLASH current (2 beam deliveries (back and forth) per each module)
** additional 2 or 3 beam deliveries 245 MeV at FLASH current might be needed to find the minimum DDC232 FSR that does not saturate the signal.
* Pristine Bragg peak measurements at clinical current for full clinical range:
** 19 beam deliveries from 245 MeV and 240 to 70 MeV in 10 MeV steps.
* Pristine Bragg peak measurements at FLASH current for full clinical range:
** 19 beam deliveries from 245 MeV and from 240 to 70 MeV in 10 MeV steps at FLASH current.
*** if there is FLASH beam time limitation we can take less energies points. Moreover, we could reduced the acquisition time for each FLASH beam delivery.
* Spot scanning:
** pristine Bragg Peak measurements at fixed energy (i.e. 150 MeV and 245 MeV) and clinical current shifting the beam up, down, left and right wrt isocenter by 3mm
*** 4 beam deliveries per energy

=== Setup ===

* Peli case set up on FLASH station.
* Network connected through TIFPA experimental room patch panel:
** Inside experimental room:
*** Long cable from patch panel (1) to DLink switch.
*** Long cable from switch to QuARC.
*** Short cable from switch to profile monitor DAQ laptop.
** Inside control room:
*** Long cable from patch panel (5) to GL.iNet Slate router.
*** Short cables to laptops.
* Case aligned to room lasers:
** Blocks used for levelling.
** Set up on height adjustable platform.
** Aligned to front cover plate.

== Measurements 29/09/2025 ==

* Approximately 100 minutes running 29/09/2025 (20:50–22:30).
* Peli case set up '''without''' movable stage: 1cm block under front, ~3mm under rear to level case.
* Isocentre at upstream face of first stack (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics are '''different''' between CONV mode and FLASH mode:
** Other than FLASH shoot through measurement with stack 1, running restricted to CONV mode.
** Current sufficient at maximum ion source current to almost saturate QuARC).
* SciFi monitor '''not''' installed.

=== General notes about the electronics ===

* Hamamatsu C9118-02 operated in Low Gain
** In low gain the dark output voltage is typ. 0.005 mV, max 0.1 mV
** The saturation output voltage is min. 3 V typ 3.5 V
* MCLK 1 MHz. Suggested min. reset time 10us and suggested min. integration time 17+4x128 clocks = 529 us.
* FPGA high period of RESET clock (reset) = 50 us, low period (integration) 950 us.* Link to the datasheet

== Measurements 01/10/2025 ==

* Start time 20:23.
* Approximately 125 minutes running 30/09/2025 (20:23–22:30).
* Peli case set up '''without''' movable stage.
* QuARC modules removed: SciFi monitor only installed at front of rails.
* Isocentre approximately aligned with first SciFi array (level with inner edge of wheel mounts).
* Alignment checked with in room lasers after each adjustment.
* Beam optics '''only''' using CONV mode.
* '''No QuARC data recorded'''.
* '''Cover plates accidentally left on for all measurements except last 2 with film'''.
* Derig completed 23:00.

=== High Gain Saturation Measurements ===

* Saturation measurements with SciFi high gain setting.
* '''Cover plates accidentally left on for all measurements except last 2 with film'''.

=== Spot Size Variation Measurements ===

* Keep high gain setting.
* Spot size variation from 70MeV with 300nA ion source current.
* Ascertain optimal current at 228MeV to be just below saturation.
* '''Cover plates accidentally left on for all measurements except last 2 with film'''.
